|Fauja Singh is 102 years old. At the age of 100 he set 5 world running|
records for his age group in one day. He attributes his physical fitness
and longevity to abstaining from smoking and alcohol and
to following a simple vegetarian diet.
Dietary Protein Decreases Exercise Endurance Through Rapamycin-Sensitive Suppression Of Muscle Mitochondria, American Journal of Physiology, Endocrinology and Metabolism, October 2013
"Loss of physical performance is linked not only to decreased activity in daily life but also to increased onset of cardiovascular diseases and mortality. A high-protein diet is recommended for aged individuals in order to preserve muscle mass; however, the regulation of muscle mitochondria by dietary protein has not been clarified.I wonder if this is related to the anecdotal evidence that people who remove meat and other animal food from their diets experience more energy:
We investigated the long-term effects of a high-protein diet on muscle properties, focusing especially on muscle mitochondria. Mice were fed a high-protein diet from the age of 8 wk and examined for mitochondrial properties and exercise endurance at the ages of 20 and 50 wk.
Compared with normal chow, a high-protein diet significantly decreased the amount of muscle mitochondria, mitochondrial activity, and running distance at 50 wk, although it increased muscle mass and grip power. Inhibition of TORC1-dependent signal pathways by rapamycin from 8 wk suppressed the decline in mitochondria and exercise endurance observed when mice were fed the high-protein diet in association with preserved AMPK activity.
Collectively, these findings suggest a role for dietary protein as a suppressor of muscle mitochondria and indicate that the age-associated decline in exercise endurance might be accelerated by excessive dietary protein through rapamycin-sensitive suppression of muscle mitochondria."
Details: I hear you're vegan now.
Mike Tyson: Yeah, it's been eight months with this vegan stuff, but I get these explosions of energy. I don't know how long they last, but they're like explosions. So powerful.
